Compress Image to 20 KB
This free tool reduces your pictures to 20 KB each, right inside the browser. Plenty of websites, government portals and application forms cap uploads at a fixed size, and a file that is even a little too large gets rejected. Instead of guessing with a quality slider, you add your photos and every one is brought to 20 KB at the best quality that still fits.
Why compress to 20 KB
20 KB is one of the most requested sizes on government and exam portals, especially for photos and signatures on recruitment, university and public service forms. If your form says the photo must be under 20 KB, this page is set up for it.
Quality and size at 20 KB
20 KB is small enough for strict forms yet large enough to keep a face clear and easy to recognise. Most portrait sized images reach 20 KB with only modest quality loss, and the original width and height are usually kept. For an even smaller file, try compress to 15 KB. For higher quality with more room, use compress to 25 KB.
Compress many images at once
Add a single picture or a whole batch and each one is compressed to 20 KB on its own. Every file keeps its name with the size added, so they stay easy to tell apart. Download any image with its own button, or use the download button to save them all together in a ZIP when you have more than one. It works the same on a phone and a computer.
Common questions about 20 KB
Why do so many forms ask for 20 KB? It is a balance the portals like: small enough to store millions of uploads cheaply, large enough to show a recognisable face. That is why exam and government sites use it so often.
What size photo suits 20 KB? A passport style head and shoulders photo around 35x45 mm or 2x2 inches compresses to 20 KB while staying clear enough to pass review.
Does 20 KB work for a signature too? Yes, easily. A signature uses far less than 20 KB, so it stays crisp.
Other target sizes
Need a different limit? You can also 5 KB, 10 KB, 15 KB, 20 to 50 KB, 25 KB, 30 KB, 40 KB, 50 KB, 100 KB, 150 KB, 200 KB, 300 KB, 500 KB, 1 MB and 2 MB. For any custom size, use the image size reducer.
